Just starting out setting up my first HA system. Something that I thought would be really easy to do was get my wifi connection set up. But things aren’t working correctly.
I plug in my use wifi adapter (RT8191SU). I see that HA detects the usb event and even lists the device:

I plug the dongle into my ubuntu laptop and its LED flashes. No lights when I plug into my odroid-n2 box.
Tried following this guide:
- no luck.
I get this:
➜ ~ nmcli radio
WIFI-HW WIFI WWAN-HW WWAN
enabled enabled enabled enabled
➜ ~ nmcli device wifi rescan
Error: No Wi-Fi device found.

What gives? Isn’t this a fairly generic wifi adapter? Why would the HA OS not detect this? Is there a way to install the drivers? Is there another wifi adapter that is preferred?
Thanks!
